Answer:

20% or 1/5.

Step-by-step explanation:

Out of ten cards, the chance of getting an odd number is of course 50% or 1/2 since half of them are odd and the other half are even. Then the chance of getting a card less than 5, or 1, 2, 3, or 4 is 40% or 2/5. Multiply these together and half of 2/5 is 1/5 so your answer is 1/5 or 20%.
